CONSTRUCTION OIF HORIZONTAL COKE OWENS WITH REGENERATORS.

.application led July 13,

T0 all whom t ma? concern.'

Be it known that l, WALTHER HIBY, a subject of the German Republic, residing at Noordwijk aan Zee, the Netherlands, have invented certain new and useful Aimprovements in the Construction of Horizontal Coke Ovens with Regenerators (for which l filed an application in Germany Aug. 15, 1916), of which the following is a specification.

rlh'e present invention relates to regenerative-coke-ovens, the regener-ators 0f which are underneath the floor of the ovens andarranged in the direction of the length of the individual oven and in which ovens the even and odd-numbered flues are alternately directly heated. ln these ovens the heating gas is led first into the first, third, fifth, ete., heating flue and burns upwardly, and the burnt gases pass downwardly into the second, fourth, and sixth, etc., Hue. After the reversal of the direction of heating, about every 30 minutes, vthe heating gases are supplied to the second, fourth, sixth, etc., lues and burn upwardly and the burnt gases de-` scend into the first, third, fifth, etc., heating lue. In these constructions the air is admitted for the total length of one oven at one timeon the left side of the oven and the combustion products travel to the right side towards the chimney and the next time after reversing the air is admitted on the right side and the productsf combustion travel on the' left side to the chimney. ln ovens of this kind the gas is introduced by burners of special width, while the distribution 0f the air, commonly introduced through one or two sole-lues, is generally regulated by dampers at the upper end of the vertical flues. lt is found by experience that these dampers should be placed in such a way, that the damper openings are widest at the end of the oven where the yair enters and narrowest at the end towards the chimney. In ovens when the draught-direction is reversed from time to time these dampers are 1norrectly placed for the distribution of the stir when flowing in one direction but are vincorrectly placed for the opposite direction. IThe present invention avoids this objection and in coke-ovens built accordingly the air is always admitted from one side and the waste-heat goes always to the other side.

C and D the invention is shown in connection with sub-heated regenerative-coke-ovens with vertical heating-dues, where the regenerators are placed between the soles of the ovens and the arches of the substructure and in which ovens the l'lues are directly heated alternately in the evenand uneven-numbered heating-lines.

Figure A is a vertical longitudinal section of the coke oven, the plane of the section passing thru a heating wall;

Fig. vB is a transverse section taken on lines BB and C@ of Fig. A;

Fig- C` is a horizontal transverse section taken on lines DD and EE of Fig; A;

Fig. D is a sectional detail of a modified form.

Between the oven-chambers 1 are located the heating-walls 2 with the uneven-numbered fines 3 and the even-numbered flues d; to each Hue 3 corresponds a burner pipe 5 and to each flue 4l a burner pipe 6'. rl`he burner pipes 5 and 6 receive gas from gaspipes in the sub-ways underneath the ovens and they discharge the gas into the heating flues at the height of the floor of the ovens. ln the construction, shown on the drawing, each regenerator is subdivided by a number of partition-walls into small checkerwork-chambers, but this is not material as the transverse partition-walls may be omitted.' According to the drawing each heating flue 3 with burner 5 has a checkerwork-chamber 7 and each heating flue t with burner 6 a checker-work-chamber 8.

The chambers 7 and 8 lie always in pairs underneath the floor of one oven and they are separated by the heavy supporting struc- The chambers 7 receive air or deliver the waste-heat through sole-tlues 9, the chambers 8 through sole-fines 10. Each sole-flue 9 has an air-admissionvalve 11 and a waste-heat-outlet-valve 13; each sole-flue 10 has valves 12 and la' respectively. All the valves for gas and air are operated by one common-reversing mechanism. v

ln the position of the reversing mechanism, shown on the drawin. the gas is admitted through burners 5 an the air through valves 11, sole-lues 9, checker-worl-r-chambers 7 into the heating-fines 3; the wasteheat escapes through dues 4c, chambers 8, sole-dues 10, valves 14 to the stach-flue 15.,
